One of Bollywood's most legendary romances could well be rekindling. Katrina Kaif, they say, has gone back to Salman Khan.

Not so long ago, both Katrina and Salman were shouting from the rooptops that they were single. "But not anymore. They have reconciled their differences and are back together as a couple," says a source.

One good indication of this patch-up is Bodyguard, Salman's sister Alvira's directorial debut, slated for Eid 2011, now a pretty auspicious date for the Khans given the stupendous success of Dabangg. Sources confirm that Katrina is slated to play the female lead.

Alvira always wanted Katrina for Bodyguard, but Sallu and Kat parted ways. In the interim, she approached Asin but it didn't work out. Salman, despite his 'split' with Katrina, has green-lit his sister's foray into direction, with Kat opposite him.

Alvira's husband, Atul Agnihotri, said, "To be frank, there's no one we'd like to see more in this film than Katrina. The truth is that neither Salman nor her has any inhibitions about working with each other. In fact they are already doing a song for Farah Khan's film. This goes to show how thoroughly professional they both are.

We should be ready to make an official announcement about the casting in a couple of days. The only hitch may be Katrina's dates, which are still being worked out. We have already decided on an Eid release so everything is being worked backwards from this proposed release date. We're trying to sort things out and are hoping for the best."

Is it love again for these two then? Surely it's been a difficult time for Katrina; despite her alleged dalliances with some co-stars, she cuts a lonely figure in the corridors of tinsel town. Salman, after all, has truly nurtured her talent from her struggling days; it is a gratitude Kat can't seem to ignore.

Likewise, the split was never acrimonious, even by Sallu's turbulent standards: neither badmouthed the other. So much so, that Katrina even recently broke down when her broken relationship with Salman was probed into at a recently-held press conference.

From what we hear, Salman is equally happy to have Katrina back in his arms. In fact, he now wants to settle down with Kat as the buzz goes. Says a source, "Salman's ego might not have allowed him to say so publicly, but he has invested nearly seven years in Katrina now. He may have had his share of flings, but he wants to marry Katrina eventually."
